JOHN CONNER, OF PITTSBURG, PENNSYLVANIA.

DRILLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 523,787, dated July 31,1894.

' Application filed April 5, 1893. Serial No. 469,238. (No model.)

To all whom, it may concern: 7

Be it known that I, JOHN CONNER, ofPittsburg, in the county of Alleghenyand State of Pennsylvania, have inventeda new and useful Improvement inWell-Drilling Apparatus, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 is a sideelevation, partly broken away, of my improved apparatus. Fig. 2 is anelevation of the opposite side of the machine. Fig. 3 is a plan view ofthe same; and Fig. 4 is a detached sectional view, showing the ropeconnection at the end of the walking-beam.

My invention relates to the portable machines used for drilling wells,whether for oil, water, gas or other substance; and it consists in acompact and simple arrangement of the parts, together with a novel meansfor actuating the tools while spudding the well, all as hereinafter morefully described and set forth in the claims.

In the drawings, in which similar numerals indicate corresponding parts,2, 2, represent the side beams of a framework supported upon the wheels3, and carrying at one end a boiler 4, and at the other an engine 5.

The engine-shaft 6, which extends across the front portion of themachine beneath the steam cylinder, carries at one end a small pulley 7,and at the other a fly-wheel 8 and a belt-wheel 9. This wheel 9 isconnected by a belt 10 with the large belt-wheel 11 upon the cross-shaft12, which is arranged to actuate either the walking-beam 13, or thespuddingbeam 14.

The spudding-beam is pivoted tothe cross-.

19, depending from the walking-beam 13, may

be pivotally attached, a series of holes being provided in the crank toallow adjustment of the stroke. The walking-beam, which extends from thecrank at an angle to the sidebeams, as shown in Fig. 3, is pivotallysupported upon the post 21, and terminates in front of the centralportion of the machine. In order to give spring to the tool-rope, aspring 50 is connected with the eye-bolt 51 at the end of thewalking-beam 13, the temper screw being connected with the eyeof thebolt. This spring should be of sufficient tension to support the weightof the rope and tools. I

' Between the pulley 7 and'a double rimmed wheel 22 upon the bull-wheelshaft 20, extends the loose belt 23, and around the second rim of thiswheel extends the brake-band 24, the two ends of which are secured tothe two arms of the bell-crank lever 25, the lower arm of this leverbeing connected by a link 26 with a second bell-crank lever 27, the arm28 of which is extended to form a handle for working the brake. Beneaththe arm .28 is .pivoted the lever 29 carrying at its end, be-

neath the belt 23, a pulley 30, by means of which the belt 23 may betightened so as to communicate a rotary motion to the bullwheel shaft;

In the rear of the bull-wheel shaft is pivoted the sand reel shaft 31,carrying at its outer end the friction-wheel 32, which may be broughtinto contact with the inner portion of the rim of the wheel 11 androtated thereby. The shaft 3l-passes at one end through the swiveledbearing 33, and at the other end through abearing carried inthe swinginglink 34, which is pivoted at 35, and is pivotally connected at its lowerend with the long rod 36, which connects with the lever 37.

Between the uprights 38 at the front of the machine is pivoted theswinging mast 39, which carries the sheave 40 for the cable, and whennot in use this mast may be swung into horizontal position, as in Fig.1, for convenience in transportation. v v

The operation of the device is obvious. In starting a well, thewalking-beam is disconnected from its crank, and the spudding-beam isemployed; and as this beam is oscillated, it moves the pulley at itsfront end and raises and lowers the tools correspondingly.

To feed the tools, the brake-lever and tightening pulley are employed,and when a considerable depth is attained, the spuddingbeam isdisconnected and the walking-beam employed. Owing to the spring 50,increased force or eifect is given to the blow of the tool.

The advantages of my apparatus will be apparent to those skilled in theart.

The device is simple, compact and cheap- It combines means for drillingdeep or shallow wells, and the actuating handles are all at the frontend of the machine within easy reach of a single operator. Thearrangement of the spudding'beam gives a quicker movement than formerly,and I intend to claim the same broadly, independently of the otherelements shown.

Many changes may be made in the form and arrangement of the partswithout departure from my invention, since What I claim is- 1. Indrilling apparatus, a wheeled vehicle carrying a pivoted mast, aspudding beam, and a walking-beam, eachisupported independently of themastand arranged to actuate successively the same working cable;substantially as described.

2. A wheeled vehicle carrying a pivoted mast, an engine, bull-wheel, andtwo swinging beams pivoted independently of the mast and arranged tosuccessively actuate the same working cable; substantially as described.

3. A wheeled vehicle carrying a pivoted mast, an engine, bull wheel, aspudding beam pivoted below the bull-wheel and having actuatingconnections with a rear shaft, and a walking-beam pivoted independentlyof the mast and arranged to be connected to the same rear shaft;substantially as described.

4. In drilling apparatus, a wheeled vehicle carrying a pivoted mast aspudding beam and a walking beam, each supported independently of themast, said vehicle having an engine, a shaft driven thereby, and havinga wheel belted to a shaft arranged to drive the swinging rope actuatingbeam, said shaft having also a pulley connected by a loose belt to thebull-wheel and means for tightening said belt; substantially asdescribed.

5. In drilling apparatus, a wheeled vehicle carrying a pivoted mast, aspudding beam and a walking beam, each supported independently of themast, said vehicle having at its front end an engine whose shaft isbelted to a rear shaft arranged to actuate the walkin g-beam, a sandreel having a friction wheel, and means for forcingthe same into contactwith'a belt wheel upon said rear shaft, a bulland the engine-shaft;substantially as described.

In testimony whereof I have hereunto set wheel, and adjustableconnections between it
